SEALED RECEPTACLE.

Specication of Letters Patent.

Patented July 15, 1919.

Application led April 26, 1916. Serial No. 93,681.

To all whom it may concern."

Be it known that I, ANDREW S. NICO, a. citizen of the United States,residin at Le Roy, in the county of Genesee and i tate of New York, haveinvented new and useful Improvements 'in Sealed Receptacles, of whichthe following is a specification.

My present invention relates to improvements in paper receptacles, andmore especially to those adapted to provide a moistureproof seal orinclosure for the contents thereof. The primary object of the inventionis to provide a novel and improved closure forsealing and securing themouth or opening of the receptacle whereby the contents thereof will beeectually retained therein and moisture will be excluded, the securingmeans for the closure, according to the present invention, being formedpreferably by bending or interlocking portions of thepaper or materialcomposing the receptacle.

To these and other ends, the invention consists in certain improvements,and combinations and arrangements of parts, all as will be hereinaftermore fully described, the novel features being pointed out particularlyin the claims at the end ofthe specification.

In the accompanying drawings:

Figure 1 is a' perspective Aview of a bag or receptacle provided with asealing closure made in accordance with one embodiment of the invention.

Fi 2 represents a section taken transverse ythrough the sealing closureshowing the seal and the securing means for maintaining the seal.

Figs. 3 and 4 are perspective views of two other embodiments of sealingclosures made in accordance with the present invention.

Figs. 5 and 6 represent transverse sections through the sealing closuresshown, respec 55 bag and composed of moisture-proof paper or similarmaterial which is folded in a manner to providev a suitable spaceforthe` contents and to bring all of the free edges of the paper ormaterial together, the margins of the paper or material being thenformed so as to seal the contents from moisture and to retain thecontents within the receptacle, and these margins of the paper ormaterial are also formed so as to maintain the seal. A receptacle ofthis general type is shown and described fully in Letters Patent, No.1,101,430, granted June 23, 1914 to Otis E. Glidden and myself. Thereceptacle shown in the present instance is of the same type as thatshown and described in said patent, but the present invention provides asealed closure which differs from that shown in said patent and whichpossesses certain advantages thereover. It is to be understood thatwhile certain embodiments of the invention are shown in the drawings andwill be hereinafter described in detail, equivalent constructions arecontemplated and will be included within the scope of the claims.

In thev present instance, 1 designates the body of the bag orreceptacle, it being made up from a blank in the manner shown anddescribed in said prior patent, that is to say, the blank is so foldedas to form a space for the contents, and the portions of the blank arebrought together at the mouth of the bag or receptacle. These portionsof the blank which are brought together at the mouth of the receptacleare designated Q. The receptacle may be made of paper of any suitablekind, but it is preferable to make it of a paper which is impervious tomoisture, a paper coated or treated with paraffin or a sO-'called waxedpaper being preferable. To facilitate handling of the paper in themachines which make up the receptacles, it is preferable to employ apaper which is waxed on the side thereof which is within the receptaclewhen the creasing causes the lapped or engaging portions 2 of thereceptacle to stand at an angle,

sharp bend and compression exerted at the corner thus formed causes theengaging and waxed-covered surfaces to conform precisely to one anotherand to form a seal which will exclude moisture from the receptacle andwill prevent leakage of the contents, especially where the contents arein` the form of a powder.

The present invention provides means formed by portions of the materialcomposing the lapped portions 2 for retaining or securing these portionsin proper engagement and for maintaining the seal formed at the angularcorner 3. In one embodiment of the invention, as shown in Figs. l and 2,a suitable number of substantially semicircular tongues 4 are punchedfrom the laterally turned portions 2, these tonguesv being bent alongthe lines 5 so asto extend angularly to the plane ofthe laterally bentportions 2, the bending of the tongues 4 at an angle to the plane of theportlons 2 forming corners between these tongues and the portions 2,which corners act in effect as interlocks, and these interlocks efcorneror along the line 3. The seal is preferably made by first compressingthe portions 2 while they stand vertically at lthe top of thereceptacle, then bending these portions 2 laterally and exerting acompression along the line 3 to form a relatively sharp bend which willproduce an effective seal, and finally punching the tongues 4 from thelaterally bent portions 2 while those portions rest upon a suitable diehaving openings to accommodate the punches and the tongues.

In the construction shown in Figs. 3 and 5, the bag may be made in thesame manner as that described in connection with the construction shownin Figs. l and 2. The seal in this latter instance is formed by the bendalong the line 3, as in the precedin instance, the marginal portions ofthe blanl; are brought together at the mouth of the bag and are lapped,as in the preceding instance, and securing tonguesare punched from theselaterally bent llapped portions 2. In this latter instance, however,these tongues, designated 4a, are of a substantially dovetail form, andthe perforations formed by the punching of the tongues extend to themargins of the laterally bent and lapped portions 2. 4

In the construction shown in Figs. L and 6, the bag may be formed ashereinbefore described, the seal being made along the bend or corner 3,as in the preceding instance, but the securing or interlocking portionsor tongues for maintaining the seal are profectuallyretain the sealformed at thel duced by slitting the laterally bent lapped portions 2along the lines 6, thus forming a series of tongues 7 and 8 spacedlongitudinally along the margin of the lapped portions 2. These tonguesare bent alternately so as to overlap opposite sides of the portions 2,the tongues 7 being turned down so as to lap the under side of theportions 2, while the alternate tongues 8 are turned up and bent toengage the upper side of the portions 2. These alternating and reverselybent tongues act to effectively maintain the seal along the corner orangle 3.

Receptacles of this character are preferably packed in cartons of suchsize that the top of the carton when closed will engage the angularly orlaterally bent portions 2, thereby maintaining these portions at theproperly bent angle during transportation. Fig. 7 is a diagrammatic viewshowing one of the receptacles in its carton 9.

To open the receptacle for the removal of the contents thereof, it isonly necessary to bend back the ton es to the plane of the lappedportions 2 orming the mouth of the receptacle, whereupon the lappedportions 2 may be readily separated to open the mouth of the bag.

Receptacles sealed in accordance with the present invention possess theadvantages, first, that the sealing operation may be performed rapidlyand easily by automatic machinery and, second, that the seal at thesealing corner or bend is effectually maintained by a mechanical lockingeffect. The use of glue or paste is .unnecessary and, moreover, wouldnot be effective when waxcoated or impregnated paper is used, and theuse of heat is unnecessary.

I claim as my invention 1. A receptacle having its material at thelapped material extending laterally fromv said corner, and means punchedfrom the lapped material and serving as a lock to prevent relativeslipping of the layers of such lapped material. V

2. A receptacle having the material at the mouth thereof lapped and bentat an angle to form a* seal at such angle, and tongues struck from thematerial forming the receptacle and at a sharp angle to the lappedportions thereof, said tongues eX- tendingtransversely of said lappedportions and operative to prevent relative shifting of the lappedportions in the direction of the plane thereof and to thereby maintainthe seal at said angle.

3. A receptacle having the material at tongues struck` from the lappedportions and bent at a sharp angle relatively to said lapped material ofthe receptacle to maintain the seal at such angle.

4. A paper receptacle having the material at the mouth thereof lappedand bent laterally at a relatively sharp angle to form a sealing corner,layers of the laterally-bent lappedl portions of the material having anincision therethrough, edges of the layers of material adjacent to saidincision being defleeted out of the planes of the respective layers intointerengaging relation with adjacent layers to thus maintain the seal atthe sealing corner. Y

.5. A receptacle having the material at the mouth thereof lapped andbent laterally, 15
